Low, gloomy clouds hung over London as we gathered in the middle of a green circular lawn outside of the LESOCO building in which Goldsmiths design students study for their masters degrees and work in their studios. Deptford creek gurgled just a few metres away, though it was closed for access by a tall metal fence. A highway overpass arced to our east and a six lane intersection around the corner made a constant soundscape of motorbikes and car engines. In this context we huddled around my turnstile radio antenna and attempted to orientate our bodies in relation to the satellite orbiting overhead and the series of urban infrastructures around us. A constant interference pattern caused audible distortion to the satellite signal and produced regular and oblique lines in the image, like counter-currents of wind or a graphical anti-pattern.
